General Information
Dear Spheros Customer,
We assume that the operation and function of your new heater will have been explained
to you properly and to your complete satisfaction by the installing workshop / service
outlet. This owner's handbook is designed to give you a brief summary of how to use the
Thermo G heater.
The heater is adjusted in the factory for use with natural gas (CNG) class H.
An unlimited use of the heater is possible up to an altitude of 1500 m above MSL and for a
short time, up to one hour, up to 2000 m above MSL (e.g. for pass crossing).
Service and safety instructions
Liability claims
For the heater exists a type approval according to the ECE Regulations R122 (Heater) and
R10 (EMC).
The heater and the gas pressure regulator must be installed as described in the attached
installation instructions.
Prior to operating the heater, check the openings for the combustion air intake and
exhaust outlet and clean them if necessary.

be operated using natural gas (CNG) of class H (methane content at least 95%) and
rated voltage of 24 VDC. If the methane content is lower than 95% (natural gas of
class L) the CO content of the exhaust gas is to be readjusted by Spheros-trained
2

personnel. The oil content of the gas must not exceed 10 mg/m .
n
be operated at least once per month for 10 minutes when the engine is cold. At the
latest when the cold weather season starts the heater must be inspected in the
context of the annual maintenance by an expert.
n
be replaced after 4 years for safety reasons. If you fail to do this, it may leak and gas
may escape.
n
be drained of oil through the oil drain screw every three months.
Failure to follow the installation instructions and the notes contained therein will
lead to all liability being refused by Spheros. The same applies if repairs are carried
out incorrectly or with the use of parts other than genuine spare parts.
This will lead to the invalidation of the type approval for the heater and therefore of
its homologation / EC type licence.
Liability claims can only be made if the claimant has verifiably considered all the
servicing and safety instructions.
n
be exposed to temperatures exceeding 100°C (storage temperature). Exceeding this
temperature may result in permanent damages.
n
be operated without at least 20% of a brand name anti-freeze in the heating system
water.
n
be shut down and the fuse shall be removed in the event of extensive smoke
development, unusual combustion noises or fuel odors. The heater must not be
used again until personnel trained by Spheros have examined it.
n
at filling stations and other refueling points.
n
if the heater or its exhaust outlet is in locations where inflammable vapors or dust
may form (e.g. close to fuel, coal, wood dust or cereal storage facilities).
n
if the heater or its exhaust outlet is located close to inflammable materials for
example dry grass and leaves, cartons, paper etc.
n
in enclosed areas (e.g. garages, hall without a suck off facility), not even if the
digital timer or Tele Start is used.
n
if the exhaust outlet of the heater is partial or fully obstructed (e.g. by soil or snow,
as it may occur while move the vehicle backwards).
